COMBTNATION VACUUM WINDOW SNAI.

Application led. February 5, 1923. Serial No. 617,056.

To all ro/0m t may concern.:

Be it known that I, OTTO G. HUBER, a citizen of the United States,residing at Hartford, in the county of Hartford and State ofConnecticut, have invented new and useful lmprovements in CombinationVacuum ViTindov-J Snaps, of which the following is a specification.

This invention relates to improvements in display devices and has for anobject the provision of means whereby various articles, such asmerchandise, display cards and the like may be removably supported uponwindow glass or other highly polished surfaces, without niarring eitherthe surface or the article.

Another object of the invention is the provision of a vacuum attachedbracket having novel means for yieldingly forcing the same away'from itssupport, so as to securely anchor the same by increasing the suctiondripping means, together with removable means for supporting articlesfrom the bracket.

lWith the above and other objects in view, the invention furtherincludes the following novel features and details of construction, to behereinafter more fully described, illustrated in the accompanyingdrawings and pointed out in the appended claims.

ln the drawings Figure 1 is a side elevation showing the inventionattached to a window glass, the glass being shown in section.

Figure 2 is a central vertical sectional View through the device.

Figure 8 is an elevat-ion at right angles to Figure 1 with the articlesupporting arm removed.

Figure l is a` top plan view of the saine.

Figure 5 is a transverse sectional view.`

Figure 6 is a detail view of one of the removable hangers or arms.

4Figure 7 is a section view of a modified form of a support attachingmember.

Referring in detail to the drawings. wherein like characters ofreference denote corresponding parts, the reference character 10indicates a section of a window glass to which the invention is applied.The invention comprises a bracket which includes an elongated body 11which is substantially U- shaped in transverse section and which carriesat each end a cylinder 12. Secured within the body 10 is a block 13preferably formed of rubber, the said block carrying a substantiallycup-shaped rubber member' 1t which is designed to provide vacuumsecuring means, as will be readily understood.

One end of each of the cylinders 12 is provided with a restrictedopening through which extends a shank 15 and secured to the outer endsof these shanks are knurled heads 16 which are adapted to providecontact members upon opposite sides of the cup 14. The inner ends of theshanks are also provided with heads 11' which act as stops to limit theoutward movement of the shanks and provide means for engagementwith oneend of springs 18 which are located within the cylinders 12 and whichact to yieldingly force the Shanks outward.

Tn' attaching the'device to a window or other polished surface, the cup14- is first moistened and then pressed` against the surface, the springpressed heads 16 yielding under this pressure so that a vacuum will beprovided between the Cup and surface to which it is attached. Theknurled head 16 will engage the attaching surface and act to increasethe suction of the cup and also prevent any tendency of the bracket tomove laterally.

The bracket is designed to support various articles such as merchandiseor display cards and for this purpose is provided with a hook 18. Inaddition, the bracket is provided with a socket 19 at the upper end ofwhich is a slot 20. This soc ret is adapted to removably receive anangularly disposed end 21 of a hanger arm 22, whose opposite end may beprovided with oppositely disposed arms 23 having upwardly bentextremities 211 at opposite ends thereof. This hanger arm which isillustrated in Figures 1, 2 and 3 of the drawings is, as stated,removable from the bracket, so that the hanger arm illustrated in Figure6 of the drawing` may be substituted. The upper end of the hanger armswill lie within the slot at the upper end of the socket 19 so as toprevent pivotal movement of the hanger arms.

Tn Figure 7 of the drawings there is illustrated a slightly modifiedconstruction, in which the knurlcd heads 16 are replaced by a disk 160and this disk carries a rubber or other cushion 25 which is adapted toengage the attaching surface for the purpose above mentioned and whichwill increase the yielding engagement afforded by the spring 18 and inaddition, will prevent scratching or otherwise marring the surface.

The invention is susceptible of various changes in its form,-proportions and minor details of construction and the right is hereinreserved to make such changes as properly fall within the scope of theappended claims.

Having described the invention what is claimed is 1. A device of thecharacter described comprising a substantially-U-shaped bracket, acylinder carried at each end of said bracket, ta. resilientblock securedwithinv the U-shapedbracket and having` cup-shaped: membermadeintegrally with and protrudingl from said resilient'block, shanksextending within and without restricted openings in said cylinders andhaving knurledy heads attached to their outer endsand heads to theirinnerends respectively, springs mounted within said cylindersand bearingagainst saidheads, a hook extending downwardly from one of saidcylinders, la socket mounted diamct-rically vopposite said resilientblock upon said bracketand having al longitudinal slot therein, and ahanger arm having' its angular disposed. upper portion received in` saidslot, and the lower portion.thereot'having upwardly bent extremities. y

2. A device of the character described comprising` a body, asubstantially U-shaped bracket,a cylinder carried at either end of saidbracket respectively, a resilient block secured-within the body portionand hava substantially said bracket, a socket mounted diametricallyopposite said resilient block upon said bracket and having,T alongitudinal slot therein, `a hanger arm having its angularly disposedupper portion received Within .sa-id slot, and the lower portion thereofhaving:r npwardly bent extremities.

3. .ai device of the class described comprising in combination, abracket,a compressiblc substantially cup-shaped member carried therebyto provide vacuum attaching means, a cylinder at each end of thebracket, a shank extending through one of the ends of each cylinder,contact heads carried at the outer ends of the Shanks, springs locatedwithin the cylinders and engaging the inner ends of the Shanks to forcethe latter outwardly and article supporting means carried by thebracket.

In testimony whereof I affix my signature.

OTTO G. HUBER
